ClinConnect Summary

This clinical trial, titled "Long Term Evaluation and Management of Atrial Fibrillation in Pacemaker Patients," is studying how often patients develop a type of heart rhythm problem called atrial fibrillation (AF), flutter, or tachycardia after getting a pacemaker. The research will involve patients who have had a pacemaker put in and are experiencing these heart rhythm issues. Over a period of five years, the study will compare the recurrence rates of these heart problems in two different groups of patients to understand the long-term effects of pacemakers.

To be eligible for this trial, participants need to be between the ages of 18 and 80 and must have developed AF, flutter, or tachycardia after their pacemaker implantation. They should also be able to safely receive a pacemaker according to specific guidelines. Participants will need to sign a consent form and commit to follow-up appointments after the surgery. It’s important to note that individuals with certain health conditions, like severe liver or kidney issues, or those who are pregnant, won't be able to participate. If you or a loved one is considering joining this study, you can expect regular check-ups and monitoring over the next five years to help improve our understanding of pacemakers and heart rhythm problems.
